What is Overclocking?Overclocking is the process of making various components of your computer run at faster speeds than they do when you first buy them. For instance, if you buy a Pentium 4 3.2GHz processor, and you want it to run faster, you could overclock the processor to make it run at 3.6GHz.

¡Disclaimer!WARNING: Overclocking can F up your stuff. Overclocking wares down the hardware and the life-expectancy of the entire computer will be lowered if you overclock. If you attempt to overclock, I, Rogue_Jedi, and Overclockers.com and its inhabitants are not responsible for anything broken or damaged when using this guide. This guide is merely for those who accept the possible outcomes of this overclocking guide/FAQ, and overclocking in general.

Why would you want to overclock? Well, the most obvious reason is that you can get more out of a processor than what you paid for. You can buy a relatively cheap processor and overclock it to run at the speed of a much more expensive processor. If you're willing to put in the time and effort, overclocking can save you a bunch of money in the future or, if you need to be at the bleeding edge like me, can give you a faster processor than you could possibly buy from a store

The Dangers of OverclockingFirst of all, let me say that if you are careful and know what you are doing, it will be very hard for you to do any permanent damage to your computer by overclocking. Your computer will either crash or just refuse to boot if you are pushing the system too far. It's very hard to fry your system by just pushing it to it's limits.

There are dangers, however. The first and most common danger is heat. When you make a component of your computer do more work than it used to, it's going to generate more heat. If you don't have sufficient cooling, your system can and will overheat. By itself, overheating cannot kill your computer, though. The only way that you will kill your computer by overheating is if you repeatedly try to run the system at temperatures higher than recommended. As I said, you should try to stay under 60 C.

Don't get overly worried about overheating issues, though. You will see signs before your system gets fried. Random crashes are the most common sign. Overheating is also easily prevented with the use of thermal sensors which can tell you how hot your system is running. If you see a temperature that you think is too high, either run the system at a lower speed or get some better cooling. I will go over cooling later in this guide.

The other "danger" of overclocking is that it can reduce the lifespan of your components. When you run more voltage through a component, it's lifespan decreases. A small boost won't have much of an affect, but if you plan on using a large overclock, you will want to be aware of the decrease in lifespan. This is not usually an issue, however, since anybody that is overclocking likely will not be using the same components for more than 4-5 years, and it is unlikely that any of your components will fail before 4-5 years regardless of how much voltage you run through it. Most processors are designed to last for up to 10 years, so losing a few of those years is usually worth the increase in performance in the mind of an overclocker.

The Basics
To understand how to overclock your system, you must first understand how your system works. The most common component to overclock is your processor.

When you buy a processor, or CPU, you will see it's operating speed. For instance, a Pentium 4 3.2GHz CPU runs at 3.2GHz, or 3200 MHz. This is a measurement of how many clock cycles the processor goes through in one second. A clock cycle is a period of time in which a processor can carry out a given amount of instructions. So, logically, the more clock cycles a processor can execute in one second, the faster it can process information and the faster your system will run. One MHz is one million clock cycles per second, so a 3.2GHz...

...and Characteristics of a CPU
Although most tech-savvy people know that the Central Processing Unit is one of the components in the computer, but not many people understand what a CPU actually does. Infact most people would not even know what CPU stands for, if you asked them today. The CPU, or microprocessor, stands for Central Processing Unit. It is a very suitable name because it describes exactly what it does in the computer. TheCPU processes instructions that it gathers from decoding the code in programs and other such files. The CPU has four primary functions: fetch, decode, execute, and writeback. In the first step, the CPU retrieves the instruction that it needs to run from program memory. Each instruction in a program (which contains millions of instructions) is stored at a specific address. The CPU has a program counter, which keeps track of the CPU’s position in the program “more specifically, the address of the instruction that the CPU is accessing”. For the next step, it is important to know no matter what code a program is written in, the compiler for that specific language is broken down to the Assembly Language. The Assembly Language is a language that the CPU understands, but may vary to different CPU’s. The “assembler” translates Assembly Language into binary code, which the CPU can manipulate to...

...The first single chip CPU was the Intel 4004 invented in Nov 1971, a 4-bit processor meant for a calculator. It processed data in 4 bits, but its instructions were 8 bits long. Program and data were separate.
In 1972, Texax Instruments followed the Intel 4004/4040 closely with the 4-bit TMS 1000, which was the first microprocessor to include enough RAM, and space for a program ROM, to allow it to operate without multiple external support chips. It also featured an innovative feature to add custom instructions to the CPU.
The 8080 was the successor to the 8008 in April 1972. While the 8008 had 14 bit PC and addressing, the 8080 had a 16 bit address bus and an 8 bit data bus. Internally it had seven 8 bit registers, a 16 bit stack pointer to memory which replaced the 8 level internal stack of the 8008, and a 16 bit program counter. It also had several I/O ports - 256 of them, so I/O devices could be hooked up without taking away or interfering with the addressing space, and a signal pin that allowed the stack to occupy a separate bank of memory. Intel updated the design with the 8085 in1976, which added two instructions to enable/disable three added interrupt pins and the serial I/O pins, and simplified hardware by only using +5V power, and adding clock generator and bus controller circuits on-chip.The 8080 was the successor to the 8008 in April 1972.

CPU - Central Processing Unit:
Pronounced as separate letters, CPU is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.
On large machines, the CPU requires one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single chip called a microprocessor. Since the 1970's the microprocessor class of CPUs has almost completely overtaken all other CPU implementations.
The CPU itself is an internal component of the computer. Modern CPUs are small and square and contain multiple metallic connectors or pins on the underside. The CPU is inserted directly into a CPU socket, pin side down, on the motherboard.
Each motherboard will support only a specific type (or range) of CPU, so you must check the motherboard manufacturer's specifications before attempting to replace or upgrade a CPU in your computer. Modern CPUs also have an attached heat sink and small fan that go directly on top of the CPU to help dissipate heat.
Two typical components of a CPU are the following:

...CPU SCHEDULING
CPU SCHEDULING MAY BE CLASSIFIED AS:
1. NON-PREEMPTIVE SCHEDULING
In Non-Preemptive Scheduling, the CPU cannot be taken away from its currently executing process. The only time the CPU scheduler can assign the CPU to another process in the ready queue is when the currently executing process terminates or enters into a Blocked state.
2. PREEMPTIVE SCHEDULING
In Preemptive Scheduling, the CPU can be taken away from its currently executing process. The currently executing process is sent back to the ready queue and the CPU scheduler assigns the CPU to another process. This will happen if:
a. An interrupt occurred so the current process has to stop executing. The CPU is then assigned to execute the ISR of the requesting device or process.
b. The priority of the process that enters the ready queue is higher than the currently executing process. The CPU is then assigned to execute the higher-priority process.
c. The time limit of a process for using the CPU has been exceeded. The CPU is then assigned to execute another process even though running process has not yet completed its current CPU burst.
Preemptive scheduling is ideally used for interactive or real-time computing systems. Non-preemptive scheduling...
